Dear Maintainer,

I installed pitivi for the first time, and on my first attempt to start it, it segfaulted:

$ sudo aptitude install pitivi
[installation process cut for brevity]
$ pitivi

Installing some of the suggested dependencies gets rid of some of the
warnings, but I can't find pycanberra in the Debian repositories. Pitivi
still segfaults:

$ sudo aptitude install gir1.2-gnomedesktop-3.0+M gir1.2-notify-0.7+M gstreamer1.0-libav+M

I don't know what else to try. It may be worth mentioning that this
happened while using the ratpoison window manager. I'm not prepared to
try it with Gnome, but it would be nice to know whether or not pitivi is
supposed to be WM agnostic.

System Information below was after installing pitivi but before
installing the suggested dependencies.

Dear Maintainer,

I ran into this startup bug too. Fortunately, searching a bit on the Internet I found a
solution below. It's said to have been included upstream so possibly it is actually fixed
in 0.94. However I could not test the package from experimental because of missing
dependencies. In any case this bug should be revisited with the new version so see if it
is fixed.

This fix is described there:
https://git.gnome.org/browse/pitivi/commit/?id=39d4a56b07d9fe2ca4216e2bea4ed4d7da9950a1

And I attached the corresponding patch for Debian.

fixed 778520 0.94-2
thank you

I tested 0.94 from testing (my desktop is pure jessie but for pitivi
and some of its dependencies) and it is indeed fixed in 0.94. I can
finally try to use pitivi.
